Recall Reference: VW Campaign 93EV / NHTSA Campaign 25V-836
If you are the owner of a 2023 or 2024 Volkswagen ID.4, please take a moment to review this critical safety warning. Volkswagen has issued a recall for specific vehicles in this model range due to a high-voltage battery defect that could lead to a vehicle fire.
Because the risk involves the potential for a thermal event (fire) while the car is parked or driving, Volkswagen has issued specific “Park Outside” instructions while they prepare the remedy.
The Issue With The VW ID.4 Battery
The problem lies within the High Voltage (HV) battery. According to the defect report, a production deviation at a battery supplier resulted in misaligned electrodes within certain battery cell modules. Specifically, the cathode inside the battery cell may have shifted. When these electrodes are not aligned correctly, it increases the risk of a short circuit inside the cell, which can lead to a fire.
Warning Signs
While a battery fire can happen suddenly, there are performance indicators you should watch for. If your vehicle has this defect, you may experience:
- A noticeable loss of driving range.
- A reduction in vehicle performance.
If you notice these issues, contact an authorized Volkswagen dealer immediately for diagnosis.
Critical Safety Instructions for Owners
Until the recall repair is performed, Volkswagen is advising owners of affected vehicles to follow these strict precautions to minimize risk:
- Park Outside: Park the vehicle away from structures and other cars immediately after charging.
- No Overnight Indoor Charging: Do not leave the vehicle charging indoors overnight.
- Limit Charge to 80%: Adjust your charging settings to stop at an 80% state of charge.
- Avoid Fast Charging: Do not use Level 3 DC Fast Chargers.
Timeline: How the Defect Was Discovered
The investigation into this issue spanned nearly two years. Here is a summary of the events that led to this recall:
- January 2024 (Illinois): Volkswagen was notified of the first thermal event involving a vehicle connected to a Level 3 DC charger. The battery was analyzed, confirming the fire started in the HV battery.
- July & October 2024 (California): Two separate fires occurred in parked vehicles that were not charging. Inspections confirmed the origin was the HV battery, but initial analysis (including CT scans by the supplier in June 2025) failed to identify the root cause.
- December 2024 (Utah): A fourth thermal event occurred while a vehicle was being driven.
- Summer 2025: With CT scans appearing inconclusive, VW and the supplier investigated other potential causes outside the battery but found nothing. The focus returned to the battery.
- August 2025 (Colorado): A fifth event occurred while a vehicle was using a DC fast charger.
- September 2025 (The Breakthrough): The supplier performed a physical “tear-down” analysis of damaged cell modules. They discovered the “shifted” electrode condition. By comparing this physical evidence back to the previous CT images, they realized the defect was visible in the scans but had been previously unrecognized.
- November 2025: The supplier identified the specific batch of bad modules, allowing VW to isolate which vehicles were affected. On November 26, VW officially decided to issue a recall.
The Remedy
Dealers will resolve this issue by replacing the high-voltage battery cell modules as necessary. Owner Notification: Notification letters are expected to be mailed by January 30, 2026.
- Volkswagen Recall Number: 93EV
- NHTSA Campaign Number: 25V-836
